Triplet states of poly(phenylene ethynylene), (3)PPE(*), not easily formed by direct photoexcitation, were produced by pulse radiolysis in toluene, along with triplet states of T(3)PPE having terthiophene end-caps. Intense triplet-triplet absorption maxima, epsilon(680)((3)PPE(*)) = 9.5 x 10(4) M(-1) cm(-1) and epsilon(780)((3)T(3)PPE(*)) = 2.8 x 10(4) M(-1) cm(-1) enable identification of thes...

Personal Protective Equipment (PPE) can be a significant determining factor between an accident and safety on construction sites. Anecdotal evidence suggests that wearing the correct personal protection at all times is extremely important in reducing accidents and should be given high priority. According to recent statistics by Occupational Safety and Health Administration (OSHA), only 64% work...

We screened seaweed species from Atlantic Canada for antidiabetic activity by testing extracts for alpha-glucosidase inhibitory effect and glucose uptake stimulatory activity. An aqueous ethanolic extract of Ascophyllum nodosum was found to be active in both assays, inhibiting rat intestinal alpha-glucosidase (IC50 = 77 microg/mL) and stimulating basal glucose uptake into 3T3-L1 adipocytes duri...

Nearly 10% of the coding capacity of the Mycobacterium tuberculosis genome is devoted to two highly expanded and enigmatic protein families called PE and PPE, some of which are important virulence/immunogenicity factors and are secreted during infection via a unique alternative secretory system termed "type VII." How PE-PPE proteins function during infection and how they are translocated to the...

UNLABELLED The purpose of this study was to investigate the effects of personal protective equipment (PPE) on cardiovascular and metabolic responses during incremental exercise, and to determine if PPE affects the relationship between heart rate (HR) and oxygen uptake when expressed as the chronotropic index (CI). Ten male participants performed graded exercise tests under three conditions: con...

In the present study possible effects of black pomegranate peel extract (PPE) on the B16F10 melanoma cells proliferation and Human Umbilical Vein Endothelial Cells (HUVECs) angiogenesis were investigated. PPE was added into the cell lines (B16F10 and HUVECs) media with different concentrations (10-450 μg/ml). After 48 h, the cell survival was measured by 3-(Dimethylthiazol-2-yl)-2, 5-diphenyl-t...

Students with special health care needs (SHCNs) and individualized education plans (IEPs) may be injured more often in vocational, career, and technical education (CTE) programs. No research to date considers personal protective equipment (PPE) use among students with SHCNs in school-based programs reporting injuries to agencies. Data from 1999 to 2011 on PPE use among injured students in CTE p...

Propolis has abundant polyphenolic constituents and is used widely as a health/functional food. Here, we investigated the effects of polyphenol-rich propolis extracts (PPE) on intestinal barrier function in human intestinal epithelial Caco-2 cells, as well as in rats. In Caco-2 cells, PPE increased transepithelial electrical resistance and decreased lucifer yellow flux. PPE-treated cells showed...

Nanoscale organic-inorganic hybrid materials were prepared from two highly fluorescent building blocks: CdTe nanowires (NWs) as an energy acceptor, and a rigid rod-like and water soluble poly(p-phenyleneethynylene) (PPE) as a donor. The PPE was covalently bonded to the CdTe by traditional amide chemistry. Two different orientations, parallel and perpendicular, of PPE to CdTe NW were achieved by...

While the preparticipation physical evaluation (PPE) is widely accepted, its usage and content are not standardized. Implementation is affected by cost, access, level of participation, participant age/sex, and local/regional/national mandate. PPE screening costs are generally borne by the athlete, family, or club. Screening involves generally agreed-upon questions based on expert opinion and te...
